Double Convex Lens, 3 inch (75mm) Diameter Concave Mirror, 380mm Focal Length, Spherical Edge Thickness 2.05mm, Optically Glass Lenses, Ground Edges, Polished, for Physics Classrooms

Features

• High Quality Optical GlassCrafted from premium optical glass, our double convex lens ensures flawless light refraction for precise imaging. Ideal as magnifying lenses, telescope lenses, or laser lens components. The smooth, polished surface minimizes distortion, making it perfect for high-power optical applications like machine vision lens setups or science experiments
• Precision DimensionsWith 3" (75mm) diameter and 8mm center thickness, these sphere lenses fit most optical instruments. The 2.05mm edge thickness ensures durability as convex lenses glasses or concave mirror alternatives. Perfect for optical concave convex lens prism sets and scientific measurements
• Superior Teaching ToolTransform abstract optics into tangible learning These circle lenses demonstrate light refraction clearly, making them essential educational aids for teaching convex lens principles, fres-nel lens comparisons, and fire starter optical lens demonstrations
• Lab-Grade DurabilityOptically processed glass construction resists wear, maintaining stable performance as magnifying glass components or eye lens replacements. Outperforms standard glass convex lens sheets for long-term use in school labs and research
• Versatile Optical SolutionFrom science museum displays to fire-starting magnifying glass projects, these double optical lenses serve multiple roles. Compatible with w/optical lens systems, concave mirror setups, and professional optical lenses arrays for diverse applications
